French officials voiced outrage Wednesday after it emerged a gang had locked up and attacked a Jewish youth in the same Paris suburb where Ilan Halimi (pictured) was tortured to death two years ago.

Six youths from the southern Paris suburb of Bagneux, aged 17 to 25, are accused of locking up 19-year-old Mathieu Roumi in a storage room on February 22, beating and sexually tormenting him.

Aged 17 to 25, the six youths -- who knew the victim -- had falsely accused him of stealing from them in order to lure him into a trap, judicial sources said.

Once he arrived in the apartment of one of his aggressors, the young man was handcuffed on a radiator and beaten.

With a pen, the aggressors scrawled "dirty Jew" and "dirty faggot" on the face of their victim. Later they forced him to swallow down cigarette butts and to suck a condom on a stick. The man’s ordeal reportedly lasted nine and a half hours.

He was later hospitalised "in a state of shock". He lodged a complaint.

They identified themselves as members of the "Barbarians," the same gang that kidnapped Halimi from his store, demanded ransom for his release, and when that was not forthcoming, tortured the 23-year-old over the course of three weeks. Moments after he was dumped on the street, Halimi died.

Roumi told police investigators that throughout his ordeal, his assailants employed measures with sexual and sadistic connotations. When the issue of his sexual orientation arose, one of them placed a condom on the tip of a stick and shoved it in Roumi's mouth.

"We admire Youssouf Fofana!" they shouted at him, referring to the leader of the gang that murdered Halimi. Fofana and 29 other suspects are on trial for abduction, torture and murder. If convicted, they can expect a life sentence.
